Sorry If ive asked this before but is there a Detailed route map of every station on the route because I keep stopping at the wrong station!
Thanks

Thanks
Nath
that looks very similar to the map that comes with NWM
On the reply page scroll down and click on the "Manage Attachments" button. There you can upload the file and it will appear with your postI have a Word Doc file showing all of the speed checks from Edinburgh-Aberdeen (Per Don's Route). Is there a way I can attach it to this Forum for others to see or download? I would appreciate your comments, thanks.
Bill,
Just to (hopefully) expand on one or two of the points that you made...
Intermediate block sections are a concept that applies only to absolute block sections - you're absolutely right to say that they're used to break up what would otherwise be a lengthy section, but if the section is track-circuited throughout, and that's used to automatically work the 'intermediate' signals, then it's simply track circuit block throughout. From the driver's point of view, the main difference (to modern standards, at least) will be that the 'intermediate' signals will be plated with an auto plate (i.e. two horizontal white stripes) instead of an IB plate.
Hopefully you'll understand the obvious cost benefit of retaining absolute block working over a section, but with an intermediate block section - the line need only be track circuited to the end of the IB home signal's overlap...whereas, with full TCB, it'd need to be track circuited throughout the section.
I'm also slightly puzzled by the references to Carmont IBS on the diagram...but no mention of Carmont box itself! I assume that there is still an operational box at Carmont? Where are the IB signals in relation to the box itself? Same goes for Marykirk! I'm just not sure whether the name refers to the location of the IBs, or the name of the controlling signalbox!
Methinks there's some confusion arising here - are you sure that you're not describing Carmont as a pair of IB signals (controlled from the box in rear!) when it should really be described as a proper block post with an operational signalbox?
I've got some diagrams that I can upload tomorrow, if there's still a bit of confuddlement - hopefully that'll help sort it out!
Edit: Sorry Bill, this was in response to the previous post, not yours!
